Well, you can certainly choose to do business with cable companies that tell you exactly what's in the cable, like ZenWave.
As far as the wire, there aren't that many companies in the world that make wire from scratch. Neotech supplies likely hundreds of companies including Siltech, Wireworld and ZenWave. That does NOT mean our cables are the same. I have some products that are made exclusively for ZenWave, and other companies have their own designs manufactured by Neotech to their specifications as well. Some of these are top-end cost-no-object cables or wire that costs ridiculous amounts of money, but they also make normal cable at normal prices too. IMO, it makes sense to understand what you're paying for, but in the cable world often this is not the case, with people willing to buy cables they have no clue what's inside and they also don't make sure connectors are genuine and the cable is properly designed.
Above and beyond buying a cheap cable for top dollar there are other aspects of cable buying I think you should consider:
1.
Connectors: There are tons of fake or look-alike connectors being sold with top-end cables including stuff posted right here on WBF. Nobody seems to care. marmota talks about using cheap Neutrik on 5-figure cables. Well, at least the manufacturer isn't hiding what they are using or selling you fakes! I honestly don't get why so many cable companies get a pass on this?
2.
Air or Fabric Dielectrics: Your cable will corrode. No, this is NOT ok and whether it's silver or copper it's simply BAD DESIGN and POOR ENGINEERING. Full Stop. You are buying garbage. We just had a cable thread where it was stated that the cable in question uses an air dielectric and NOBODY bats an eye! Why would you possibly want to buy a a cable that's going to corrode over time? This is also either dishonest or the designer is a complete idiot. OTOH, I agree that air is a better dielectric and sounds better, but it won't work out long-term. The only way to do this properly is to use an INERT GAS dielectric, but this is difficult so you get 5-figure cable makers that are too lazy to protect your investment by using an inert gas because air is easy. It's everywhere! But yeah, it's only a lowlife that thinks it's ok to sell cables that will certainly degrade over time.
3.
Durability: So many ribbon or foil cables that can't be bent without putting too much stress on the cable, and so many cables that use heavy-gauge solid-core wire... If you put a ribbon side by side and terminate it into an RCA or XLR connector you can't bend it without the cable quickly failing due to massive amounts of stress placed on the terminations and insulation. Solid-core wire is NOT intended to be bent repeatedly, it is intended for PERMANENT installation. In the recent past, right here on WBF people are hawking power cables made with heavy-gauge solid-core wire. The same person recently hawking air dielectric cables. These are horrible designs. With a power cable you'll get an increase in resistance each time the power cable is bent and eventually you'll get too much resistance, which will cause heat. This is how toaster ovens work, and is to be avoided at all costs in power cables for what should be obvious reasons.
Anyways, I need to get back to work, but this is a subject that really bothers me. I totally understand you want to get good value for your money when buying anything but complaints about not getting high end connectors, etc. with your $10k cables when other companies are selling you blatant fakes, cables that are unsuitable to act as cables because they can't be bent without damaging them, and cables that make no effort to prevent them from corrosion are all much more important factors that seem to always be ignored. You complain that the same companies make wire for multiple companies, which is the way almost every industry works, but are ok with buying cables that are made out of "secret" wires?
I can only help this will assist some with seeing the larger issues involved with cables. I hope this will encourage you to only buy cables from companies that are transparent about what you're really getting for your money. There is so much misinformation and I think the real issues that plague the cable industry are left unaddressed and ignored.
